m is the mass corrected for buoyancy using densities listed in Table 1, ΔTc is the corrected temperature rise, ϵ (cont) is the energy equivalent of the contents of the bomb, ΔUign is the ignition energy, and ΔUIBP is the energy of the isothermal bomb process, which was calculated by ΔUIBP = [ϵ (calor)(−ΔTc) + ϵ (cont)(−ΔTc) + (ΔUign) (ΔUcorr)]. ΔUcorr is the correction to standard state and Δcuo (7M4MC) is the 7-methoxy-4-methylcoumarin mass energy of combustion. The uncertainty corresponds to the expanded uncertainty with a confidence level of 95%.
